Высокопатогенный грипп птиц является особо опасной высококонтагиозной вирусной инфекцией домашних и диких птиц, в последние годы получившей широкое распространение на территории стран Европы, Азии, Африки и Америки. Возбудитель заболевания – вирус гриппа типа А подтипов H5 и H7. Одним из наиболее быстрых и эффективных способов идентификации и типирования вируса гриппа птиц является ОТ-ПЦР в режиме реального времени, в связи с чем представляется актуальной разработка тест-системы на основе данного метода с использованием внутреннего контрольного образца для возможности контроля основных этапов проведения реакции. При этом постановка реакции в мультиплексном формате позволяет одновременно идентифицировать несколько целевых мишеней, что уменьшает расход реагентов и время постановки реакции.</p></sec><sec><title>Цель исследования</title><p>Цель исследования. Разработка тест-системы для выявления в пробах биологического материала РНК вируса гриппа птиц подтипов H5 и H7 методом мультиплексной ОТ-ПЦР в режиме реального времени и определение ее основных характеристик.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Использовали изоляты вируса гриппа птиц подтипов H5, H7, H3, H4, H10, H16, вирусы ньюкаслской болезни, инфекционной бурсальной болезни, инфекционного бронхита кур, болезни Марека и аденовирус птиц. В качестве внутреннего контрольного образца служил бактериофаг MS2.</p></sec><sec><title>Результаты</title><p>Результаты. Подобраны оптимальные сочетания систем праймеров и зондов, определены характеристики тест-системы: специфичность в отношении гомологичных и гетерологичных вирусов болезней птиц, аналитическая чувствительность, эффективность реакции амплификации, повторяемость и воспроизводимость.</p></sec><sec><title>Заключение</title><p>Заключение. При определении валидационных характеристик разработанной тест-системы установлена ее специфичность в отношении только вируса гриппа птиц подтипов H5 и H7, аналитическая чувствительность для каждого подтипа составила 1,5 lg ЭИД50/см3 , эффективность амплификации – 92 и 97% соответственно. Проведена апробация тест-системы при исследовании поступающих в лабораторию проб биологического материала, результаты соответствовали таковым для стандартных диагностических методов, используемых в референтной лаборатории вирусных болезней птиц ФГБУ «ВНИИЗЖ».</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. High pathogenicity avian influenza is a dangerous highly contagious viral infection of domestic and wild birds that recently has become widespread in Europe, Asia, Africa and Americas. The causative agent of the disease is type A influenza virus of subtypes H5 and H7. Real-time RT-PCR is one of the most rapid and effective techniques for avian influenza virus identification and typing, so development of the test system based on this technique with internal control to be used for control of the reaction main stages is of current importance. At the same time, the multiplex format of RT-PCR allows for simultaneous identification of several targets that reduces the consumption of reagents and the reaction time.</p></sec><sec><title>Objective</title><p>Objective. Development of test-system for detection of H5 and H7 avian influenza virus RNA with multiplex real-time RT-PCR in biological samples and its characterization.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. H5, H7, H3, H4, H10, H16 avian influenza virus, Newcastle disease virus, infectious bursal disease virus, infectious bronchitis virus, Marek’s disease virus, avian adenovirus isolates were used. MS2 bacteriophage was used as internal control.</p></sec><sec><title>Results</title><p>Results. Optimal primer-probe combinations were selected, test-system characteristics were determined: specificity for homologous and heterologous avian disease viruses, analytical sensitivity, reaction amplification efficiency, repeatability and reproducibility.</p></sec><sec><title>Conclusion</title><p>Conclusion. Determination of the developed test system validation parameters has shown that it is specific only for H5 and H7 avian influenza virus, its analytical sensitivity for each subtype was 1.5 lg EID50/cm3 , and the amplification efficiency was 92 and 97%, respectively. The test system was validated through its use for testing biological samples submitted to the laboratory, the test results were consistent with the results of tests with standard diagnostic methods used in the Reference Laboratory for Avian Viral Diseases of the Federal Centre for Animal Health.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>высокопатогенный грипп птиц</kwd><kwd>вирус гриппа птиц подтипа H5</kwd><kwd>вирус гриппа птиц подтипа H7</kwd><kwd>ОТ-ПЦР-РВ</kwd><kwd>тест-система</kwd></kwd-group><kwd-group xml:lang="en"><kwd>high pathogenicity avian influenza</kwd><kwd>H5 avian influenza virus</kwd><kwd>H7 avian influenza virus</kwd><kwd>real-time RT-PCR test-system</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена за счет средств ФГБУ «ВНИИЗЖ» в рамках тематики научно-исследовательских работ «Ветеринарное благополучие».</funding-statement><funding-statement xml:lang="en">The study was funded by the Federal Centre for Animal Health within the research topic “Veterinary Welfare”.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Lycett S.
